now televisions and movies become the two kinds of essential ways to entertain. but should parents limit the hours of watching TV programs or movies to let their children get a high score in school?  this question has caused a fierce discussion among people. someone agree with that, while others not. but from my own prospection, the time of watching TV programs and movies has no direct influence on children's study.to get a high score, children must work hard, obtain scientific method of study, and pay attention to the rest as well, since a healthy body may be the base of great success. as for the parents, the most important is to give encouragement to their children rather than forcing them to study harder and harder. of course, reasonable entertainment is a must. my cousin for example, he is a brilliant boy, and my uncle and ante give him the enough space to do his own work. they don't limit his life, so he can do whatever he want. but when he is studying, they will turn down the TV, and lower their voice of talking. while he has stress on study, they will relax him, such as traveling. so my cousin is always the best in his class.what TV programs and movies include is about entertainment, or education like records of actual events. children can know about these kinds of content to broad their horizons, get relax and them have a greater efficiency on study.what is more, this can help children do better in their study. besides, the high or low score typically base on how hard the children work. playing computer games with no limitation, having negative attitude to study are the fundamental factors that influence children's study. early times in china, great quantities of teenagers spend their times in the web bars. they treat the games more important than any other things in their lives. there is no doubt that computer games have ruined a large amount of children's lives.in my opinion, limit the time is not a effective way to the children. it is the contents that influence more on study. parents should not allow their children to watch such kind of program about sex or violate. they can let them watch some educational program that will help them with study.
